. UNITED STATES This invention relates to means for incinerating refuse-and its main. object is to provide means for the above purpose that are of greater, efliciency and economy than those otnommonly in use. In certain of the incinernearer refuse which are now onthe market $18 a feature to use a small grate at the lower art "and under the grate to place a burner, also. to employ a plurality of small 10 pipesextending from the grate to one. ide of the same, andthen to extend said pipes upward to remove thewaste ases from the burnerwithout utilizing sue gases above Said grate. In my improved incinerating 5 means I make use of such gases in drying r container therefor and pass the hot gases from the gas or other burneror other suitable source perpendicularly upward alon "fa it is dry enough to ignite, after which the 'f' combustion of the material itself aids the drying of the ortion of the mass further removed from he flaming ortion, and such -.1 25 drying is still further assisted bythe hot gases and flame from the burner or burners until all the refuse that is combustible is reduced to ashes. I

In connection with the improved method described above I have devised novel means for carr ing out the same efiicientl and ecol nomically as will appear in the escription of said means in detail hereinafter. The means I prefer to employ to accomplish the an. above ob ects together with other features ofmy improved means of incinerating refuse, are illustrated in the drawing accompanying and forming part of this specification and in which 49 Figure 1 is a vertical section through one form of my invention taken on the line 1-1 of Figs. 2 and3. a I Fig. 2 is a vertical section taken on the line 22 of Figs. 1 and 3. Fig. 3 is a horizontal section on the line it 3-13. of Figs. 1 and 2. a I

L 'ke characters of reference refer to like parts in all the figures of the drawing.

In the form of my invention illustrated in 1 Figs; 1 to 3 incluslve, the numeral 2 indicatesan u right casin for the incinerating means and which pro erably consists of an i outer portion or wall 3 and an inner portion or wall 4 which is preferably supported 55 by an angle member 5 secured to the outer the mass ofirefuse in the greater part of the I thlo'side or sides and ends of said mass unti HARRY L. cowrss, or mew YORK, N.

wall Ordinarily a lining 6 of refractory material such as fire brick is suitably su ported inside of the wall asby means of t e member/7. For holding the refuse for in-' cineration I preferably employv a container or compartment such as indicatedby 8 ill.-

the various figures of the drawing and which I is formed as shown therein of L-shaped metal bars such as 9 suitably supported. Preferably the supporting means for said bars take the form of metal bars such as 10 and '11 at the upper parts and bars 12 at the lower parts of the L-shaped bars 9.

The bars 10 and 11 are supported in any suitable way such. as by angle members 13 secured to the wall 4, and the bars 12 pref-' erably are supported by resting them on a portion of the lining 6. In Flgs. 1 and 3 two containers or compartments 8 are employed which are separated by a flue 15 which also extends around the ends of the containers so as to form a capital letter H in the horizontal section. The bars 9 have openings 16 between them which openin at their upper parts communicate with t e flue 15. i

I Any suitable means for drying and ignite ing the refuse in the containers 8 ma be employed but preferably I employ a fl ame which will play against the bottom part of the container, and I allow the hot gases from said flame or. hot gases and flame also to pass up the flue 15 acting on the sides or side and also on the ends of the mass of refuse similarly as on the bottom of the same. Ordinarily I employ a burner adapted to burn fluid fuel such as illuminating gas or the like and the flame from the burner is directed against the bottom of the container 8 and its acts first to dry and finally to ignite the refuse through the openings 16, and the hot gases from the burner, or a portion of the flames together withthe hot gases pass up said flue and dry the sides or sides and ends of the mass through the openings 16 between the bars 9, the gases finall passing out of the flues 15 laterally throu h the openings 17 and over the top of t e refuse, and thence to the outlet pipe 18.

In the drawings 20 indicates the burner and 21 refers to the piping therefor'and 22 is the mixer for minglingair with the gas supply. Ordinarily I provide apan 24 under the burner or burners to catch ashes and any water which drips-down from the which is directed of its refuse container and flows along the 6. The combination with a casing, and two refuse containers secured to the walls thereof and having perforated side walls forming a common, vertical flue between themand portions at the lowerparts forming floors .of the containers, of means for burnin fluid fuel under the containers which inc ude a portion under each of them provided with .a member adapted to divide the stream of flame into two parts one of which parts passes directly up said flue and the other of ainst the lower rear part bottom of the same into said common flue.

7; The combination with a casing, and a.

refuse container secured to the wall thereof and having a perforated side wall which asi in forming a vertical flue and a perforated floor portion at the lower part,v of means for producing a stream of flame below the container which stream flows upward toward it, and a member adapted to divide said stream into two parts one of which passes directly into said flue and the other of which 7 is directed against the lower rear part of the refuse container and flows along the bottom of the same into said flue.

8. The combination of a casing, two refuse containers therein having a common flue between them whose walls are formed as separate frames composed of a multiplicity of substantially vertical portions with openings between them and means to connect and support them on the inside of the casing walls, floor portions having perforations which portions are arranged at the lower parts of said containers transverse to the sides of the common flue, means to support said floor portions, and means below the containers for effecting the drying and igniting the contents of the same.

9. A refuse incinerator embodying a casing, a refuse container in said casing having upright walls, one of which is formed by awall of said casing, and other walls of said container forming a connected frame having an apertured wall extending across the container and two end walls transverse to the first-mentioned wall, and means to support said frame whereby an upright flue of restricted width is formed next to said container walls and partially surrounding the container.

10. A refuse incinerator embodying a casing, a refuse container in said casing having four upright walls, one of which is formed by a wall of said casing and also including, an apertured side wall and two apertured end walls, said apertured walls forming three sides of a rectangle and being adjacent to and forming walls of an upright flue of restricted width, one portion of which extends across the incinerator and joins transverse portions along the end walls i and partially surrounding the container.

11. The combination with an incinerator having a casing','of a refuse container having upright walls, one of which is formed by a wall of said casing and also including A three walls or partitions arranged to form three sides of a rectangle and said casing wall forming the fourth side thereof, the opposite container wall being apertured and also forming a wall of a vertically disposed flue of restricted width partially surrounding the container, one part of which extendsacross the incinerator, said container walls being substantially parallel respectively to the other three upright casing walls.

12. A refuse incinerator embodying a casing, and two opposite refuse containers therein having upright Walls, one of each of which is formed by a wall of saidvcasing, each having an apertured side wall opposl'te the other refuse container, and two apertured end walls, said apertured walls ibeing adjacent to and forming walls of a fine H-shapsd in horizontal section whose middle portion extends across the incinerator and is formed by-said apertured side walls, and arefuse container surrounded by the casing. v

13. A refuse incinerator embodying a casing, two opposite refuse containers therein having upright walls, one of each of which is formed by a wall of the casing, each having an apertured side wall opposite the other,

container and substantially parallel to the casing wall, said two apertured walls forming an upright flue adjacent to each of said containers, a double inclined, apexed roof portion over said flue, and a smoke outlet hi her than said apexed roof portion and su stantially in alinement with thesame.

14. A refuse incinerator embodying a casing, and two opposite refuse containers therein, each having an apertured side wall opposite the other refuse container and two Signed at New York, in the count-y of New York, and State of New York, this 1st day of April, 1927. HARRY L. COWLES.
